Abstract

A multicarrier communication apparatus (1) includes: a scheduler (12) operable to schedule transmission opportunities of the plurality of series of transmission data in accordance with predetermined scheduling information; a peak evaluator (18) to evaluate whether or not the peak of the multicarrier signal exceeds a predetermined threshold value; and a peak suppressing unit operable to halt transmission of at least some of the plurality of series of transmission data based on the scheduling information upon decision by said peak evaluator (18) that the result of the evaluation exceeds the threshold value. This construction makes it possible to accomplish peak suppression with ease without increasing the arithmetic scale, like in the previous art, while maintaining communication of users high in scheduling precedence.
